Title:
TOOL ABRASION EVALUATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/189911
Kind Code:
A1
Abstract:
Provided is an evaluation device (20) capable of evaluating the abrasion state of a tool by visual means without affecting machining time or machining precision. The present invention is provided with a vibration detector (21) for detecting machining vibrations produced when a workpiece (W) is machined by a tool (T) using a machine tool (1), a frequency analyzer (22) for performing a spectrum analysis of vibration data detected by the vibration detector (21) using a predetermined sampling interval, a contour diagram formation unit (24) for forming a contour diagram that expresses in different colors the intensity of the frequency components each time interval on the basis of the frequency spectrum sequentially analyzed by the frequency analyzer (22), and a display device (26) for displaying on a display (27) the contour diagram formed by the contour diagram formation unit (24).
